Abstract

The study examined soil fertility status under different land use types and its management practices in Bure district of Illubabor zone, southwest Ethiopia. A structured questionnaire survey of 546 randomly selected smallholder farmers was employed to collect data, along with focus group discussions, key informant interviews, and personal observations. In addition, thirty-two composite soil samples were taken at a depth of 0-30 cm from forest, grazing, and cultivated lands to determine soil fertility status. The data were analyzed using ANOVA and descriptive statistics. The findings of the soil analysis showed that the distribution of soil particle sizes, available phosphorus, total nitrogen, soil organic carbon, organic matter, and cation exchange capacity varied significantly (p<0.05) between forest, grazing, and cultivated lands. The findings also showed that when land use and cover shifted from forests to cultivated and grazing lands, soil fertility decreased. The pH of the soil under cultivated land was found to be highly acidic, while the soil under forest and grazing lands was found to be strongly acidic. The most widely used soil fertility management practices were the application of miner fertilizer, building of bunds, planting of vetiver grass, contour plowing, crop rotation, straw and mulching, and agroforestry practices. The findings of this study suggest that in highly acidic soils found in cultivated lands, applying an adequate amount of lime can help to enhance soil fertility and boost land productivity.

Abstract

Environmental and land resource degradation is a serious problem that poses significant challenges in Sudan and worldwide generally. Despite the fact that the physical environment components are the underlying economic resources and production assets in developing countries like Sudan, and they directly affect the nation’s socioeconomic aspects of income, health, water availability, food security, and many others. The interventions and protective measures were insufficient to meet the magnitude and extent of the ongoing degradation and resource wastage. Based on the analysis of the indicators and trends of the environmental and natural resources management ‘status quo’, this paper is an attempt to overview and investigate the state of environmental and natural resources management and governance in Sudan. Further discussion delves into the utilization of geo-information systems in Sudan’s environmental and resource management by analyzing and reviewing “some previous case studies” where GIS approaches and techniques were deployed. The paper further strives to explore and highlight the opportunities and potential contributions of GIS in the context of Sudan’s environmental and resource management. Lessons learned from the previous experiences were considered, and the recommendations for the future use of a tailored geo-information system in Sudan context were highlighted and suggested to support better practices and sustainability insights for environmental governance and resources management.

Abstract

Duku (Lansium domesticum) is an endemic plant in Indonesia with various benefits and distinctive tastes that many people favor. Duku originating from Kudus is known as Duku Sumber, one of the five superior duku varieties. The problem encountered today is the decreasing number of Duku Sumber plants due to land use change, and there has been no effort to increase the plant population. Information on land suitability as a basis for developing crops does not yet exist, so data about land suitability will be used as information on the wider distribution of planting areas in Kudus. This study aimed to evaluate the suitability and land use of Duku Sumber plants in the Kudus Regency. Geographic information systems and matching methods were applied to map the distribution of land suitability for Duku Sumber. The results showed that the potential and actual land suitability class for Duku Sumber are very suitable (S1) and quite suitable (S2) for the Jekulo, Hadipolo, Tenggeles, Golantepus, and Megawon areas, while the slightly suitable (S3) are Klaling, Ngembalrejo, Mejobo and Jati Wetan. The availability of nutrients (na) for nitrogen and potassium is the dominant limiting factor in this area. Nitrogen content in Jati Wetan (0.12%), Klaling (0.19%), and Hadiwarno (0.19%), while potassium content in Ngembalrejo (16.47 ppm) and Mejobo (18.57 ppm). Limitations in this area can be overcome by adding nitrogen and potassium fertilizers to become suitable land.

Abstract

Groundwater is utilized as a clean water source including in Pelauw and Kariu Villages. Drilling and excavating are frequent techniques utilized in the construction of wells that serve as sources of groundwater. As a result of the ocean encircling the majority of this area, salinity may infiltrate wells. Consequently, the purpose of this study was to ascertain whether seawater intrusion had occurred in 12 nearby wells. Major ion tests were carried out in the lab, while surveys and measurement fields were carried out for the sampling procedure. Ion Cl, EC, TDS, Simpson ratio, and BEX data are used in the analysis to determine whether seawater intrusion is present. Additionally, the Piper diagram is used to categorize different types of water based on the outcomes of the main ion test. The findings indicated that Cl-, EC, and TDS levels have increased at a number of the sampling sites. At point A09, there is an indication of seawater intrusion based on the BEX values, which shows a negative number. The majority of the well water, as determined by a water classification analysis using the Piper diagram, is of the calcium carbonate type. Meanwhile, the remaining portion is separated into the calcium sulfate and sodium bicarbonate types.

Abstract

Peri-urban forests are wooded areas under the influence of urbanization and are becoming increasingly attractive as recreational areas for urban populations. This study focused specifically on the El Meridj-Est recreational forest, located in Constantine, the capital of eastern Algeria. This study selected this forest as the main case study because of its distinction as the region's most frequented woodland site. This research aimed to understand the practices of 350 users of this forest and to identify the determining factors behind the high affluence at El Meridj. This study also examined their individual and family perceptions, expectations, and concerns, adopting a methodological approach combining detailed qualitative and quantitative social survey techniques. This study fills a research gap in the field of peri-urban green space management with regard to social interactions and recreational activities in these spaces. It also highlights the importance of taking local specificities into account when studying recreational spaces. These results, potentially generalizable to other similar geographical and cultural contexts, offer practical perspectives for the management and conservation of peri-urban forests while minimizing the negative impacts of anthropogenic pressures leading to the degradation of these natural environments.

Abstract

Ultisol dry land is characterized by significantly low organic carbon content, an important factor influencing soil water content and physico-chemical dynamics. The addition of N fertilizer dissolved in seaweed liquid extract as an enrichment solution can change the character of biochar. Therefore, this study aimed to analyze the characteristics of cogongrass biochar enriched with dissolved N fertilizer in seaweed extract of different species and assess its impact on soil water content in Ultisol. Urea was used as a nitrogen source, and biochar enriched with N fertilizer dissolved in seaweed liquid extract from Kappapychus alvarezii, Sargassum sp., and Ulva lactuca was tested. Biochar dose used was 20% of soil weight with a 10% extract concentration for each type. Furthermore, five-level treatments were tested in a pot experiment, namely (i) without biochar, (ii) biochar unenriched, (iii) enriched with N fertilizer dissolved in K. alvarezii extract, (iv) enriched with N fertilizer dissolved in Sargassum sp. extract, and (v) biochar enriched with N fertilizer dissolved in U. lactuca extract. Each treatment was repeated three times, following a randomized block design. The results showed that cogongrass biochar enriched with N fertilizer dissolved in seaweed extract had a more amorphous surface morphology structure. The proportion of elements and functional groups in cogongrass biochar changed. Enriched biochar increased Ultisol moisture levels, but water holding capacity and retention were lower than the unenriched sample.

Abstract

On September 28, 2018, a 7.5 Richter magnitude earthquake struck the Palu City neighborhood of Petobo. The tectonic activity along the Palu-Koro fault generated this earthquake, which resulted in soil liquefaction. The purpose of this study is to use microtremor measurements at 33 distinct places to investigate the properties of the soil layer after liquefaction. The obtained data was then evaluated utilizing Horizontal to Vertical Spectral Ratio (HVSR) methodologies such as Ground Shear Strength (GSS), amplification factor, and vulnerability index to determine the soil layer's properties and susceptibility. The dominant frequency ranges from 0.19 to 4.75 Hz, while the dominant period ranges from 0.21 to 5.17 seconds, according to the measurement results. According to these measurements, the silt layer varies between 5 and 30 m. GSS values in the 10-4 to 10-2 range indicate that soil cracking, subsidence, liquefaction, landslides, and compaction are likely. The soil vulnerability and amplification index values range from 2.36 to 4.37, respectively. These values show the potential level of danger, which might be low, medium, high, or extremely high. Peak ground acceleration varied from 299.52 to 301.52 gals, suggesting high to extremely high danger levels. The microzonation map created for this study is considered to be a useful resource for training disaster mitigation approaches and facilitating infrastructure development planning in the region.

Abstract

The concerns about the conversion of swamp land into settlements and its effect on the quality of river water are urgent in Indonesia as a developing country. This research evaluated how changes in land use in the Keramasan region of Palembang, South Sumatra, affect the water quality of the Pedado River. Physical, chemical, and microbiological characteristics of the water were gathered in 2017 and 2022 from four monitoring points along the Pedado River. Pollution indicators were used to evaluate the state of river water quality. The results showed that land conversion operations increased flow from the mainland into the Pedado River and the loss of swamp vegetation. One such activity in 2022 was the backfilling of 42.92 hectares of swampland. Total suspended solids (TSS), copper (Cu), oil, and fat in the Pedado River surpassed the quality limits of class II, according to Government Regulation of the Republic of Indonesia Number 82 of 2001, based on measurements of the water quality in the Keramasan region. The Pedado River's water pollution status changed from mildly contaminated in 2017 (pollution index: 3.728-4.940) to moderately polluted in 2022 (pollution index: 5.395-6.236). These results highlight the critical need for thorough water treatment and preventative actions to lessen further contamination in the Pedado River.

Abstract

Post-mined reclamation is an essential phase in coal mining operations, ensuring that the ex-mining area can function again according to its intended purpose in the future. This study aimed to elucidate the differences in planting years of post-mined reclamation at a coal mine in the Paringin area, South Kalimantan, Indonesia, and compared them to undisturbed areas for the years 2003 and 2023. NDVI was used for land cover analysis based on the Ministry of Energy and Mineral Resource Regulation, and the ultimate criterion for 100% success in post-mined reclamation is vegetation canopy coverage. The NDVI results showed an improvement in NDVI values for the post-mined reclamation area from 2003 to 2023, indicating an improvement in land cover due to the revegetation process. In 2023, the NDVI results of the post-mined reclamation for eight and twenty years of tree planting showed NDVI values of 0.6-0.7 (moderate vegetation). However, the results of field observations of the twenty-year post-mined reclamation tree condition indicate the non-survival of fast-growing tree species, such as Albizia chinensis. The composition of fast-growing and local tree species, with a minimum proportion of 60:40, and systematic tree distribution across the post-mined reclamation area are required to maintain canopy coverage of the post-mined reclamation area in the long term. Fast-growing tree species, as pioneers, have short to medium life periods. Therefore, the ultimate criterion for 100% success in post-mined reclamation for canopy coverage should be based on local tree species, serving as the basis for releasing the reclamation bond.

Abstract

The hydrological function of peatlands, one of which is acting as a medium for storing and releasing water, undergoes alteration due to degradation. Saturated hydraulic conductivity (Ks) is a pivotal parameter for comprehending the hydraulic properties of peatlands. Ks plays a crucial role in the transmission and release of water influenced by other peat properties. This research examined the impact of Ks and selected peat properties, namely bulk density and available water content, to depict the hydrological function in rewetted peatlands. The study sites are rubber plantation (RB), oil palm plantation (OP), and drained secondary forest (SF). Results revealed a significantly higher Ks in OP (106.7 cm hr-1) compared to RB (19.56 cm hr-1) and DSF (15.1 cm hr-1). The hydrological function at all study sites was categorized as high, with minor degradation in OP and moderate degradation in RB and SF. Nonetheless, these findings necessitate fundamental interpretation and adjustment. The outcomes of this study can be utilized to prioritize rewetting efforts in the study sites, emphasizing the importance of prioritizing immature peat (fibric) with high Ks.
